Hi,
I just attached a second changer and found a glitch in the chio-changer script 
while testing it with bacula.
I attached the patch to fix it.
Kind regards,

 I've added your fix to the source, but in looking at the 
 line, it seems to me 
 that it is not going to handle things correctly.  Could you 
 send me the raw 
 output from:
 
${MTX} -f $CHANGER status slot
 
 Thanks.

RE: [Bacula-users] RE: [Bacula-devel] autochanger update slots bugfix

2006-01-09 Thread Alexander Kuehn 
I assume it's because of the preceeding whitespaces from wc, unfortunately the 
error channel from the script is discarded so I'm only 99.98% sure ;) (imho 
stderr should be echoed back to the console).

~  chio -f /dev/ch0 status slot|wc -l
   6
~  chio -f /dev/ch0 status slot|wc -l|bc
6
~  

Maybe someone else with a similar setup can check if this problem is 
reproducable? (FreeBSD 5.4-STABLE and FreeBSD 6.0-STABLE, do update slots for 
a check). At least here it's definitely not working without the the '|bc' but 
working with it. 
On the other hand I don't think the additional bc will break anything (at 
least) in the *BSD world (which is where chio is used) since bc is part of 
base. I guess a line in the release notes is due anyway.
Kind regards,
Alex

 Thanks for the output.
 
 It is interesting to see how chio actually works.  However, I 
 don't understand 
 the need for a call to bc since wc -l' at least on my system 
 returns a 
 perfectly valid count (in fact the same thing as wc -l | bc.

 Hello,
 I'm trying to get this schedule to run at night, but time 
 wise it runs
 during the day during system peaktimes, can someone tell me where my
 thoughts went wrong?
 Thanks.
 Dave
 
 # schedules 
 
 
 Schedule {
  Name = sat_fdd
  Run = Full sat at 11:00
  Run = Differential sun-fri at 12:00
 }

Hmm, just a guess, but I would read this as sun,mon,tue,wed,thu,fri at 12:00 
(noon)
If it's supposed to run at night maybe what you want is:
  Run = Differential sun-fri at 00:00  ?

 
 # This schedule does the catalog. It starts after the WeeklyCycle
 Schedule {
   Name = WeeklyCycleAfterBackup
   Run = Full sun-sat at 3:30
 }

Kinds regards,
Alex.

[Bacula-users] parallel spooling/despooling

2005-08-30 Thread Alexander Kuehn 
Hi,

I have a [EMAIL PROTECTED] FreeBSD machine with a DDS3 Streamer attached to it. 
The streamer does about 1MB/s, when I use Bacula I can monitor the machine and 
streamer usage using systat -vm, when I do that I see that nothing is running 
at full steam, the streamer does about 0.8 MB/s, the CPU is at 80% usage, the 
harddisk is 5-20% usage. Of course this varies over time, but these values are 
pretty typical. I was wondering if I could optimize the usage to minimize the 
backup times. I was very happy to see that Bacula supports spooling at first, 
but I was kinda set back when I saw that spooling and despooling is done 
sequentially not in parallel. I had already set up a mfs based /tmp (128MB) to 
have Bacula spool to RAM (which the machine has plenty of), and CPU usage was 
indeed 100% as I had expected. Of course the CPU was basically unutilized when 
it came to unspooling the file.
I wonder if it would be difficult to modify Bacula to use two spool files 
instead of one, so that:
fd starts collecting files and creating the normal spool file,
as soon as it is ready and signals sd to unspool the file, it does not wait 
until sd has finished but continues to collect files but stores them in a 
second file, right next to the normal spool file,
as soon as sd has finished unspooling and fd spooling to the second file, the 
second file is renamed to the normal spool file and fd starts to collect for a 
new second file...
I think this way the backup time could be significantly reduced in cases such 
as this one.
Kind regards,
Alex.
